Limited decline, continuous limit-ups are rare; widespread gains hide hidden dangers

The index’s yellow line is soaring high above, with the white line supporting underneath—a classic 80/20 pattern, with weights holding the stage and themes performing. Although the index rebounded on lower volume, individual stocks generally rose, showing excellent profit-making effects. Short-term rally emotions may have some disconnect, but core high-value stocks remain firmly grouped, and computing hardware and robots have become the main focus of capital.

Before an in-depth review, a routine summary of today’s observations:

In the afternoon, attention to Huasheng Tiancheng decreased at high levels;
In the afternoon, attention to Tuowei Information decreased at high levels;

Deep Dive: Market Sentiment Review
$1
Tuesday, March 10, 2026

1. Core Data and Sentiment Diagnosis
1.1 Overall Market Performance
Today, the major index surged like a spring tide, up 26.54 points, closing at 4123.14. Although trading volume shrank to 2.3979 trillion, it still remained at a high level of 2.3 trillion, like a tidal flat after the tide recedes—water level drops but remains moist. The number of advancing stocks reached 4,302, while declining stocks were only 790, a broad rally.

From a sentiment perspective, 55 stocks hit the daily limit up without ST tags, only 4 hit the limit down—an extreme contrast, with bears nearly defeated. However, detailed relay data shows signs of “fear of heights”: the upgrade rate from first to second board is 13%, and from second to third is also 13%, indicating very low willingness among funds to chase mid-cap stocks, mostly suffering from “fear of heights,” only daring to pick initial breakout stocks or high-positioned groups. Only one stock exceeds four consecutive boards. The limit-up break rate today was 28.57%, within controllable range. Yesterday’s limit-up stocks rose an average of 3.46% today, indicating premiums are still acceptable, and there’s no panic button being pressed by funds.

2. Deep Analysis of Continuous Boards
Today’s continuous board hierarchy shows a “pyramid” shape, steepening towards the top, with capital focusing on core stocks.
5 boards: 1 stock—Wangli Security, 5 days of 5 boards, high market prominence, involved in robotics, Huawei, security, with volume reduction and cautious approach.
3 boards: 1 stock—Ningbo Construction, 3 days of 3 boards, core in computing power leasing (crayfish concept), leading position, despite gaps, remains popular due to rarity of concept.
2 boards: 4 stocks—Zhongnan Culture and others, with obvious tier gaps, many failed to upgrade from second to third, mostly follow-up gains from sector fermentation, with questionable sustainability.
First board: 49 stocks—many new faces, mainly low-level gains in computing hardware and optical communications.

3. Hot Sector and Key Stock Comments
3.1 Computing Hardware and Optical Communications (AI Infrastructure)
Number of limit-ups: 9 in the sector (e.g., Hui Green Ecology, Changfei Optical Fiber).
Industry drivers: Nvidia GTC will showcase CPO, liquid cooling tech, plus fiber optic cables rising due to data center demand, industry sentiment improving.
Key stocks analysis:
Hui Green Ecology: 3 boards in 7 days, optical communication + CPO, upward trend, deep institutional involvement, steady performance.
Changfei Optical Fiber: leading optical communication company, boosted by Hong Kong stock rally in the afternoon, A-shares hit the limit, institutional support, positive trend.

3.2 Crayfish Concept (Computing Power Leasing)
Number of limit-ups: 5.
Industry drivers: Market hype around demand for computing power leasing, concept is scarce.
Key stocks analysis:
Ningbo Construction: core in 3 boards, leading position, sector differentiation exists but its status remains solid.
Qunxing Toys: 2 boards, following sector, but stocks like Meili Yun have fallen back after hitting the limit, indicating sector divergence, caution needed for later-stage rotation.

3.3 Robots and Intelligent Manufacturing
Number of limit-ups: 5.
Industry drivers: Market expectations for humanoid robot industrialization, driven by Wangli Security’s high targets.
Key stocks analysis:
Wangli Security: 5 boards, market sentiment anchor, energizing the robotics sector.
Xuelong Group: stimulated by news of holding shares in Yushu Technology, following the leader’s rise.

4. Overall Market Sentiment Analysis
Currently, the market is in a “index supporting, theme performing” oscillating upward cycle. Although volume has decreased, funds have not exited but are more focused on core themes.

Future outlook: Short-term index is stable, but watch for divergence after volume contraction. The market will shift to a phase of “light index, heavy stocks,” emphasizing the sustainability of core themes.

Focus areas:

1. Computing hardware: optical communications, PCBs, liquid-cooled servers, etc., look for low-entry opportunities in trending stocks.
2. Robots: monitor Wangli Security’s sustainability; if it breaks through high resistance, the sector may see a second wave.
3. Computing power leasing (crayfish): watch Ningbo Construction; if it can break through sector divergence, there’s room for late-stage gains.

Remember, mid-cap stocks (2-4 boards) carry high risks—only experienced traders should attempt relay.
